Question 4 While conducting a survey to learn about employee satisfaction, a data analyst notices that the majority of respondents are people who work in the operations department. The fairness of their survey could be improved by over-sampling which employees?

The fairness of the survey could be improved by over-sampling employees from departments other than operations. This would help ensure that the survey results are representative of the entire organization and not biased towards the opinions and experiences of those in the operations department.

Specifically, the data analyst should consider over-sampling employees from the following groups:

- Employees from departments that are underrepresented in the current survey results.

- Departments such as finance, marketing, sales, human resources, IT, and others.

- Any specific subgroups within the company that may have different experiences or satisfaction levels.

By doing so, the analyst can achieve a more balanced and comprehensive understanding of employee satisfaction across the entire organization.
